Be it known that I, HENRY K. Forum,

I citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Treating Roads, of which the following is a specification.

This invention relates to apparatus for applying asphaltic road oils, and emulsifying pils, or any bituminous products-either hot or cold-toroads, for their maintenance, and construction, and also for the purpose of laying dust.

It is the object of the resent invention to provide an apparatus of the kind stated by means of which the material can be readily heated and distributed in any desired volume, from the lightest to the heaviest a pli- -cat1on, and as evenly and as unifoim y asthough applied by a brush."

A further object of the invention is to provide an a paratus which will handle all kinds of 011s, of any consistency or grade, withequal facility, a heater being provided by. means of which the oil may be heated so that it will flow freely, thus permitting the use of heavy oils, and also enabling the apparatus to be operated in cold weather.

1 The invention also has for its objectto provide an apparatus of the kind stated embodyingscertam novel features of construction: to be hereinafter described and claimed, reference being bad to the accompanying :drawings and the detailed description ,ap- 'p'earin hereinafter. A

In t e drawings-Figure 1 is a side ele :vation of the apparatus. Fig. 2 is a rear end View thereof. Fig. 3 is a lon 'tudinal section "taken on the line 3r-3 0 Fig. 2. Fig. 4 is a bottom plan view of a fragment.

of one of the spra er. pipes; Fig. 5 isa cross section of sai pipe taken on theline '5 5+5 of Fig. 4. Fig. 6 is a sectionaldetail through one of the corners of the tank and fire box showing the construction thereof.

a I Referringspecifically to the drawings, 10 denotes a rectangular steel tank which is mounted on a platform spring, turn-under,

running gear, the wheels 11 of which are fittedwith'broad tires.

Atthe front end of the running gearjsa-seat 12 for the driver. Beneath. the tank is a fire box 13 extending throughout the entire length and width} thereof, and containing liquid-fuel burners down the side walls of ing the fire box.

ning ear behind the tank 10. A force feed is ha by placing the-,fuel in the tankunder pressure by means of an airpump 16 14, fed from a tank-15f mounted discharging into said tank. The fuelitank, 9

is fitted with a pressure gage 17 to indicate; the air pressure therein. The fuel, supply ipe 18 running from the tank to the burners, is provided with a valve 19, so that. the

flames of the burners may be increased, di

minished, or extinguished. The firebox .is provided with a'door 20 through which access to the burners-is had, and above the door is located aflashboard 21 to prevent any ofthe contents of the tank which might 7 slop over and run down the side thereof, from running into the fire box.'

The running gear carries longitudinalT- rails '22 on which the -tank 10 and the fire box 13 are sup orted. The webs. ofthe rails are upstan ing, and to the outer surfaces thereof are riveted, or otherwise. 'se-' cured, the side walls of the tank, said walls being extended to form the side walls of the fire box. The bottom 23 ,of the tank forms the top of the fire box, and is riveted,

the rails 22, said flan es being horizontal.

The lower ed es of t e side walls of the tank rest on the outer flanges of the rails. The object of this construction is to prevent, any-of the oil which may slop over and run hrough the tank 10 extend'flues are arranged vertically, and open 'at the r lower ends into the'fire box 13. The flues the tank from enterare arranged in two groups located, respec t'ively, at the front and rear ends of'the tank, one of the burners 14 being located under each group. The upper ends of the flues of each group open into .a removable smoke box 26 mounted on top of tlie tanltf l'fi and fitted with astack 27 The; produotsfof combustion pass from the-,fire bo'i{ '1 nj t 'ti;the ;flues, and pass out of the. sa'mej' 'intojthe smoke box, from which .latterflthey escape byway of the stacks. InasmucHija'sfthe flues pass through the tank, tli'e -co'ntents thereof are rapidly heated. A thermometer 28 is connected to thetank so that the temperature of the contents thereof 'may'beobserved.

means ofa. suitable {tackle connected to the crane, and the latter is pivoted to the" tank as indicated 'at' 33 so that it may be swung engageable-with suitable keeper 36, holds into horizontal position, out of the way when not in use, it being supported in this posi tion by a bracket,34.

The contents of the tank 10 are distributed over the road by means of the spraying devices which will now be described; To the bottom of the tank. is connected a pipe 37 provided with a. gate valve 38, and having a rearward extensionfliiggf to the extremity; of which is connected a cross coupling :40 containing a strainer Thebr-anch of the eross-coupling opposite the oneto which the pipe 39 is connected, is closed by a plug 42,; and to the other branches of'the cross coupling are connected two oppositely extend, ing pipes 43, the cross coupling being ar,

ranged so that said pipes 43 are horizontal. To the extremities of each pipe 43 is connected a coupling 44 which carries the spray pi pe 45, two of such pipes being provided, they being connected to thecouplings 44 by suitable fittings 46,"in which latter are inter posed gate valves 47. Each spray pipe is from both of said pipes maybe controlled.

The spray pipes are arranged in and in the same horizontal plan and each has two rows of outlet apertures 4d arranged staggered. The couplings 44 are provided with clean-out plugs 49.

The valves 47 are operated by means of hand levers 51 connected to the, stems of said valves, and fulcrumed on stems To theback of the cover is hinged a foot piece 31-which is designed to engage parallelism e The apertures 48 are not drilled on radial lines, but they extend parallel to a perpen- 52 carried by the fittings 46, the free ends of the levers working-in guides 53 carriedby the couplings 44. The pipes 45 carry a seat. 54, the latter being located so that the operating means of the valves 38 and 47 are within easy access of the operator occupying the seat.

The spray pipes-45 are divided into two sections by a partition 55 locatedmidway-between the ends thereof, so that either one or both sections of thepipes may be used by a proper manipulation of the valves 47. The partition'is' so located that'there is no of the pipes are inuse'.

To the bottom of the tank 10 is also connected a rearwardly'extending pipe 56 provi-dedwith avalve 57, and open at'itsend,

qsaidpipe being. provided inorder that the .oil'forlother material in the tank may be removed for anypurpose, and in anyquantity,

by. simply placing a bucket-or other receptacle under thedischarge'end of the pipe, .and opening the valve.

. To the couplings'44 are secured sprinkler" heads. 5 8'-'-in 'order -that the apparatus may also be used for fjsprinkling water. The

structure of the sprinkler heads is immaterial to the present invention, and a detailed description thereof is, therefore,

"deemed unnecessary. The sprinkler heads are voperated by suitable devices having actuating rods extending to the drivers seat.-

It will be understood, ofcourse, that the tank 10 will be filled with water when the apparatus is tobe, used for sprinkling water, and'the valves -47' will then also be closed- I claim; 1. ,The combination with a vehicle run-, ning gear, of a tank mountedthereon, a fire box under the tank, T-rails. on "the running gear, said rails having theiriwebs' upstanding, and the side walls of thejtank being extended to form the side wallsof the fire box, and secured to said..upstanding webs on the outside thereof, the bottom of .the fire box being secureldto the inner 'horizontalflanges ""break in the discharge when both sections of the T-rails, and a spraying device connected to the tank.
